Ap\u00f3s um ano de desenvolvimento foi publicado<\/a><\/noindex> lan\u00e7amento do projeto Stratis 2.0<\/a><\/noindex>, desenvolvido pela Red Hat e pela comunidade Fedora para unificar e simplificar as ferramentas de configura\u00e7\u00e3o e gerenciamento de um ou mais armazenamentos locais. Stratis oferece recursos como aloca\u00e7\u00e3o din\u00e2mica de espa\u00e7o de armazenamento, snapshots, garantia de integridade e cria\u00e7\u00e3o de camadas para cache. O c\u00f3digo do projeto \u00e9 escrito em Rust e \u00e9 distribu\u00eddo<\/a><\/noindex> sob a licen\u00e7a MPL 2.0.<\/p>\n

O sistema em muitos aspectos replica as capacidades avan\u00e7adas de gerenciamento de parti\u00e7\u00f5es do ZFS e Btrfs, mas \u00e9 implementado como uma camada (daemon stratisd<\/a><\/noindex>), operando sobre a subsistema device-mapper do n\u00facleo Linux (s\u00e3o utilizados m\u00f3dulos dm-thin, dm-cache, dm-thinpool, dm-raid e dm-integrity) e o sistema de arquivos XFS. Diferente do ZFS e Btrfs, os componentes do Stratis operam somente no espa\u00e7o do usu\u00e1rio e n\u00e3o exigem o carregamento de m\u00f3dulos espec\u00edficos do n\u00facleo. O projeto \u00e9 apresentado inicialmente como que n\u00e3o requer<\/a><\/noindex> qualifica\u00e7\u00f5es de especialista em sistemas de armazenamento para administra\u00e7\u00e3o. <\/p>\n

Para gerenciamento, \u00e9 fornecido um API D-Bus e uma ferramenta cli<\/a><\/noindex>.
\nO funcionamento do Stratis foi testado com dispositivos de bloco com base em LUKS (parti\u00e7\u00f5es criptografadas), mdraid, dm-multipath, iSCSI, volumes l\u00f3gicos LVM, assim como com diversos HDDs, SSDs e unidades NVMe. Com um \u00fanico disco no pool, o Stratis permite o uso de parti\u00e7\u00f5es l\u00f3gicas que suportam snapshots para reverter altera\u00e7\u00f5es. Ao adicionar m\u00faltiplos armazenamentos ao pool, surge a possibilidade de combina\u00e7\u00e3o l\u00f3gica de unidades em uma \u00e1rea cont\u00ednua. Recursos como
\nRAID, compress\u00e3o de dados, deduplica\u00e7\u00e3o e organiza\u00e7\u00e3o de toler\u00e2ncia a falhas ainda n\u00e3o s\u00e3o suportados, mas est\u00e3o planejados para o futuro.<\/p>\n

\"Lan\u00e7amento<\/a><\/noindex><\/center><\/p>\n

Em novo<\/a><\/noindex> lan\u00e7amento<\/a><\/noindex> aumentaram os requisitos para a vers\u00e3o do compilador Rust (m\u00ednimo 1.37, mas recomenda-se 1.38). A mudan\u00e7a significativa no n\u00famero da vers\u00e3o est\u00e1 relacionada \u00e0 renomea\u00e7\u00e3o de algumas interfaces do D-Bus e \u00e0 reestrutura\u00e7\u00e3o da organiza\u00e7\u00e3o do trabalho com o D-Bus (conjunto de propriedades fundamentais prim\u00e1rias foi destacado, enquanto as demais propriedades agora s\u00e3o consultadas por meio do novo m\u00e9todo FetchProperties).<\/p>\n
